The Health Sciences Authority (HSA) has come across a teeth whitening product, “Beautiful – Cold Light Teeth Whitening Kit” being sold online.  The whitening gel in the kit contains 4% of hydrogen peroxide and should only be supplied through registered dentists and used under supervision of registered dentists as it is potentially corrosive.

“Beautiful – Cold Light Teeth Whitening Kit”

The teeth whitening gel contained in the “Beautiful – Cold Light Teeth Whitening Kit” is a cosmetic product.

Products found to be unsafe will be removed from the market.
